GWYNETH PALTROW'S PBS GIG! PLUS: SHE MIGHT ADOPT!

Gwyneth Paltrow is making a comeback after taking time off to be a mom. Paltrow will star in a PBS' Spain ... On the Road Again with Mario Batali. "We'll be in a car, road- tripping," Paltrow says in the September issue of W magazine.

Paltrow will also make a return to the big screen in Iron Man, a blockbuster starring Robert Downey Jr. "It's been a long time since I've done a big part in a movie, and I'm very excited," Paltrow tells W. "Robert called me and said, 'Don't you want to be in a movie that people see?' And he's right."

Gwyn also says she's considering having more children with her husband, Chris Martin. "Maybe in four years, I'll have two in a row really quick again," she tells the magazine. "But then at that point, when everyone's potty-trained and sleeping through the night, are you really going to go back? My husband really wants to adopt. So I don't know, I'm sort of open for anything."
